Which of these is NOT a negative form of deviant behaviour?

In sociology, deviance describes an action or behavior that violates social norms, including a formally enacted rule (e.g., crime), as well as informal violations of social norms (e.g., rejecting folkways and mores). Although deviance may have a negative connotation, the violation of social norms is not always a negative action; positive deviation exists in some situations. Although a norm is violated, a behavior can still be classified as positive or acceptable.

Social norms differ throughout society and between cultures. A certain act or behaviour may be viewed as deviant and receive sanctions or punishments within one society and be seen as normal behaviour in another society. Additionally, as a society's understanding of social norms changes over time, so too does the collective perception of deviance.

Formal deviance includes criminal violation of formally-enacted laws. Examples of formal deviance include robbery, theft, rape, murder, and assault.

Informal deviance refers to violations of informal social norms, which are norms that have not been codified into law. Examples of informal deviance include picking one’s nose, belching loudly, or standing unnecessarily close to another person.
